Question

What is fragmentation?

Answer 1

Processes are stored and removed from memory, which makes free memory space, which is too little to even consider utilizing by different processes.  Suppose, that process is not ready to dispense to memory blocks since its little size and memory hinder consistently staying unused is called fragmentation. This kind of issue occurs during a dynamic memory allotment framework when free blocks are small, so it can’t satisfy any request.

Answer 2

Fragmentation is an important function of the network layer. It is a technique in which gateways break up or divide larger packets into smaller ones called fragments. Each fragment is then sent as a separate internal packet. Each fragment has its own separate header and trailer. Sometimes, a fragmented datagram also gets fragmented when it encounters a network that handles smaller fragments. Thus, a datagram can be fragmented several times before it reaches its final destination. The reverse process of fragmentation is difficult. Reassembly of fragments is usually done by the destination host because each fragment has become an independent datagram.
